Grape pomace, as by-product of wine making, is a source of polyphenols, fibers, fatty acids, metals, and organic acids, which could be used as raw component for the production of sustainable materials. Novel biodegradable films based on pomaces, from Negroamaro (red) and Fiano (white), Italian grape cultivars, were fabricated. Physical, chemical and antioxidant properties of material produced were characterized. In particular, migration tests of phenols from pomace films to aqueous food simulant medium were investigated. Data obtained allowed to evaluate the antioxidant activity in terms of total phenol assay and Trolox Equivalent Antioxidant Capacity assay and phenols profile. The characterization of phenolic composition confirmed the peculiarity of some compounds such as anthocyanins (191.17 ± 10.3 μg/g film) in red skin pomace film (NPF) and a great amount of flavanols (76.36 ± 1.72 μg/g film) in white skin pomace film (FPF). Antioxidant activity of polyphenols resulted in active films and was confirmed in migration test with aqueous food simulants. Physical properties of produced films were then studied in terms of morphological, thermal, mechanical and barrier properties. Finally, in the framework of sustainability and circular economy, the presented data paves the way to the design and production of active materials for packaging application starting from a widely available by-product derived from wine-making chain.

葡萄渣作为酿酒的副产品，是多酚、纤维、脂肪酸、金属和有机酸的来源，可用作生产可持续材料的原料。制造了基于意大利葡萄品种 Negroamaro（红色）和 Fiano（白色）果渣的新型可生物降解薄膜。对所生产材料的物理、化学和抗氧化性能进行了表征。特别是，研究了酚类物质从果渣薄膜迁移到水性食品模拟介质的迁移试验。获得的数据允许根据总酚测定和 Trolox 等效抗氧化能力测定和酚谱评估抗氧化活性。酚类成分的表征证实了一些化合物的特殊性，例如花青素 (191.17 ± 10. 红皮果渣薄膜 (NPF) 中含有 3 μg/g 薄膜，而白皮果渣薄膜 (FPF) 中含有大量黄烷醇 (76.36 ± 1.72 μg/g 薄膜)。多酚的抗氧化活性产生活性膜，并在水性食品模拟物的迁移试验中得到证实。然后在形态、热、机械和阻隔性能方面研究所生产薄膜的物理性能。最后，在可持续性和循环经济的框架内，所提供的数据为包装应用活性材料的设计和生产铺平了道路，该材料从葡萄酒生产链中广泛可用的副产品开始。然后在形态、热、机械和阻隔性能方面研究所生产薄膜的物理性能。最后，在可持续性和循环经济的框架内，所提供的数据为包装应用活性材料的设计和生产铺平了道路，该材料从葡萄酒生产链中广泛可用的副产品开始。然后在形态、热、机械和阻隔性能方面研究所生产薄膜的物理性能。最后，在可持续性和循环经济的框架内，所提供的数据为包装应用活性材料的设计和生产铺平了道路，该材料从葡萄酒生产链中广泛可用的副产品开始。
